Pindar

Pindar (518 BC – 438 BC) was a Boeotian poet, counted as one of the nine lyric poets of Greece. The only works of his to have survived complete are a series of odes written to celebrate the victors in athletic games.

Creatures of a day! What is a man?
What is he not? A dream of a shadow
Is our mortal being. But when there comes to men
A gleam of splendour given of Heaven,
Then rests on them a light of glory
And blesséd are their days.

Pythian 8, line 95-8; pages 162-3. (446 BC)

Cf. Man is a dream about a shadow.
But when some splendour falls upon him from God,
a glory comes to him and his life is sweet.
